APPAATUS FOR STRIPPING TASTE OFF SINGLE-BEADED TUBES, BOBBINS, 0R EIR-NS.

v Speccation of Letters Patent.

Patented May 30, 19t l To all whom it may concern:

Be it known that l, NORMAN Buzon W'Anknn, a subject of the King or Great Britain and Ireland, residing at Steeton, near Keighley, in the county olf-York, England, have invented a .new and useful Apparatus for Stripping lllaste ot Single- Headed Tubes, Bobbins, or Pirns, of which the following is a specification.

This invention relates to an apparatus tor stripping waste ott' single headed tubes, bobbins or pirns, and has 'for its object, the arrangement and construction or' a machine, operated either by hand or power, which will strip ott the Waste Without damaging the bobbins.

After use in the first instance, varying amounts of waste are generally lett on the bcbbin, and the usual practice is to strip or cnt the yarn or traste from the bobbin, by means ot a knife or otaher suitable l or convenient implement. Thisniethod, as

will be readily understood, cuts up the surface of the bobbin, and in course of time spoils the same, Whereas, by the use of the hereinafter described apparatus, the Waste is stripped ott without damage to the bobbin.

In describingmy invention in detail, reti erence is made to theI accompanying sheet of drawings, similar letters indicating sin1i lar parts in which,

Figures l and 2 represent trout and side elevations respectively, of one torni olf apparatus. Fig. '3 represents a plan olf the jaws or dies hereinafter referred to. t shows another form ot' apparatus, and Fig. 5 represents an operating handle.

ln carrying ont my invention, Figs. l and 2 show a form of devicen'hich is arranged to operate vertically. the apparatus being provided with a. suitable attachingorclan'iping device C, a` plunger l provided-with a rack R operates in a casing and engaging with the rack llis a pinion RL which is actuated by a suitable. handle il?. ll more power is desirable, other gear wheels or pinions may bc used.

The plunger lo) carries at one end a pairv of dies or jaws l), such dies or jawsfbt-lng formed with a cone shaped opening .l (Fig. 3) the loweredgcs ll being sonne- Wha-t,sl1arp. One of the jaws ll is prelcr ably provided w'vith a support- Dl against which the head of the tube or bobbin T rests during the operation of the apparatus. The jaws D may be provided With a spring or like S, in order to tend to keep them in the closed or gripping position, and thus make allowances for any taper in the bobbin or the like, or the spring or the like may be discarded, and the jaws pressed together by hand during operation.

ll'lounted on or attached to the casing A.

is a bracket in which works an adjustable' 65 rod or bobbin retainer E having a reduced end El for engaging with the hollow end of the tube or likefl. The rod E provided with notches oii'the like E2 (F ig. and a holding nut N is provided on the bracket B.

@n 'the plunger l) are placed adjusting collars-l.1 ana P- in order to allow of the device being set tor bobbins or tubes oit varying length.

in operation the collars P1 and P2 are set 75 at the desired points in the plunger P, the rod E is set in thevdesired position, the pointed or narrow end'of the tube T is placed on the end El oi rod F1, and the other end of the tube is pressed into the jaws or Waste 7 from the tube without in any way 85 cutting or damaging the tubesnrtace. ln

another torni the device mav be arranged horizontally and the movements carried on as betere described.

ln lfig. .t is shown a forni of apparat-us in 90 which the dies l) do not move, such dies ot jaws being arranged in any convenient manner and position; a plunger l) slides in a head G', and the bobbin or tube T is pressed through tho dies or jaws by the movement ot the plunger. ft V-sbaped rest V may be provided Ytor the tube to rest in; such rest V may be suitably hinged to the traine work or table. The. j'ilunger may be operated by any suitable mechanism. that shown in Fig. 5 100 will answer the purpose` a\\'l1erein a handle lt is pivotcd to the plunger li, and to a bracket (l1 attached to the gauntree. (l.

lt desired tbll apparatus may be actuated by power or by toot. lt will be readily i understood that the dies may be operated in other ways than those described iv1thout in any way departing from the principle hereinbefore set forth, and the tube may be rigidly held either by its head or by being A thereon, a second jaw pivotally supported thereon, elastic means normally holding said second'jaw in closed relation with respect to said first jaw, said jaws kbeing provided with recesses in their inner edges adapted to register with one another to form an opening orengaging one end of the bobbin, said pivotal point of connection being in the rear of said opening, whereby the front ends of.

said jaws lmay be separated to provide an 'entrance to'said opei'iing, a support for the other end of the bobbin, and means for causing the jaws to strip the waste from the bobbins.

2. A waste 4stripper for bobbins and the like, fcomprising a movable support, a pair of jaws pivoted thereto, means for closing said jaws, said jaws being provided with recesses in their inner edges adapted to register with one another to form an opening for engaging one end of the bobbin, said pivotal point of connection being in the rear of said opening, whereby the front end of said jaws may. be separated to provide an entrance to said opening, a support for the other end of the bobbin, and means for moving said movable support and said jaws relatively to said second support, whereby to strip the waste from the bobbin. 35 3. A waste stripper for bobbins and the l like, comprising a body portion, a plunger" 'reciprocatingly supported thereon, a rack and pinion gear operatively associated with said body portion and said plunger for re- 40 ciprocating the latter, a pair of jaws pivotally mounted upon said plunger, said jaws being provided with recesses in their inner edges adapted to register with-one another to form an opening for engaging one end of the bobbin, said pivotal point of connection being in the rear of said opening, whereby thelfront end of said jaws may be separated to provide an entrance to said opening, and a support for the other end of the bobbin carried by said body portion.

In witness thereof, I have hereunto set my hand in the presence of two witnesses.
